THERAPEUTIC CABINET.

Application led March 1, 1915.

To all wit/0m it may concern:

Be it known that I, BONNAFORD LESLIE, a citizen of the United States,and a resident of Chicago, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in TherapeuticCabinets; and I do hereby declare that the following is a full, clear,and exact description thereof, reference being had to the accompanyingdrawings, and to the characters of reference marked thereon, which forma part of this specification.

This invention relates to improvements in therapeutic cabinets of thatkind in which a heated medium and a medicated vapor are applied to thebody of the patient while 'reclining therein so as to induceperspiration and facilitate the penetration of the medicated vaporthrough the pores of the skin.

Among the objects of the invention is to produce an improved cabinet ofthis char; acter so constructed and arranged as to provide for thedirect application of the medicated vapor and heated medium to the body,and also provide for a thorough and uniform admiXture of the vapor andheated medium throughout the cabinet and a free circulation of thematerial through the conducting ipes. p Further objects of the inventionare to improve and simplify cabinet constructions of this character, andthe invention consists m the matters hereinafter set forth and moreparticularly pointed out in the appended claims.

In the drawings z-Figure 1 is a side elevation of a therapeutic cabinetembodying my invention. Fig. 2 is a partial end view and partialtransverse sectional view. Fig. 3 is a horizontal section taken on thegeneral line indicated at 3 3 of Fig. 1. Fig. 4 is a fragmentary sectionview of one of the distributing pipes. Fig. 5 is a cross section 0n theline 5--5 of Fig. 3.V

As shown in the drawings, 10, 11 designate the front and rear walls,respectively, of the cabinet boX or inclosure and 12, 12 'designate theend walls thereof. The cabinet is open at its top and isadapted to beclosed by a swinging lid or coverl hinged to one side wall. A portion ofthe front wall 10 comprises a drop door 15 to facilitate entrance to andexit from the cabinet. 16 designates a foraminated or open work supporton which the patient reclines during Specification of Letters Patent,

the treatment, and upwardly through which rear end wall of the cabinetis provided withv an opening through which the head and neck of thepatient extends and with a head rest 17 to support the head of thepatient while reclining in the cabinet.

rranged within the cabinet beneath the Said support 1G are two pipes 18,19, respectively, through the first of which is adapted to be circulateda medicated vapor, and through the latter of which is adapted to becirculated a heated medium. Each of said pipes extends from the frontend of the cabinet to a point near the rear end thereof and is connectedby a return bend (20, 21) to the return portion of the pipe,

giving a U-shape to each of the pipes. The

terminal 22 of the return portion of the vapor pipe is directedlaterally through the rear wall 11 of the cabinet and, in practice, theout-turned terminal is connected with an vexhaust pipe located outsideof the apartment in which the cabinet is contained. No means are hereinshown for supporting the pipes in the cabinet, but it will be understoodthat they may be supported in a generally horizontal suitable manner.

The induction end of the vapor pipe is connected by a iiaring mouthpiece or funn nel section 24 with a receptacle or retort 25 in which amedicated solution is heated to vaporize it, as by means of a suitablegas burner therebelow; the vapor rising through the funnel section 2dand upwardly through the external vertical portion 26 of the inductionend of the vapor pipe to circulate backwardly through the cabinet andthence forwardly to the outlet terminal 22. The said vapor pipe isperforated to permit the escape of vapor into the cabinet, theperforations being` preferably at the bottom of the pipe.

rIhe induction end 28 of the dry air pipe, exterior to the cabinet, isformed with a Haring or funnel-shaped intake 29 which is located over asuitable burnerin such manner as to direct the air heated by the burnerinto the dry air pipe, the heated air circun lating backwardly andforwardly through the continuous dry air pipe and escaping positiontherein in any ico through a terminal 30, which may exhaust through thefront end wall of the cabinet.

The 'said exhaust terminal of the dry air pipe is provided with a valve8l whereby the volume of air circulated through the pipe may be varied,and thereby the temperature to which the air is heated regulated. Thedry air pipe is also perforated, preferably at its lower side, so as topermit the escape of dry air into the cabinet.

The bottom wall 33 of the cabinet tapers or inclines from both ends andfrom both sides thereof toward the central portion, at Which is locateda'valved drain pipe 35, whereby moisture which accumulates in thecabinet may be drained or drawn off therefrom.

In the operation of the device the receptacle 25 is charged with amedicated solution, as a sulfur solution,V and the receptacle Ais placedover a burner of a suitable stove 36, which stove may support thereceptacle. The burner beneath the receptacle and also Vthe burnerbeneath the flaring induction end 29 of the dry'air pipe are thereafterlighted. VThe air heated by the burner is circulated through. the dryair pipe, and the vapoiwhich rises from the receptacle 25 is circulatedthrough the vapor pipe. The air and Vvapor are distributed uniformlythrough the cabinetby the perforated dry air and vapor pipes and mixwith each other as they rise from the pipes towardV the lsupport 1G. Thevolume of dry air passing through the pipe 19 is regulated by the valve31 and, thereby the temperature of the air delivered to the cabinet isvaried. The volume of vapor circulating through the pipe 18 may bevaried by regulating the burner flame below the receptacle r25. TherebyI am enabled to closely regulate the temperature and the amount ofmedicated vapor delivered into the cabinet. The passages through thepipes fromV the y induction ends to the outlet terminals thereof aredirect, so that the regulation maybe effected without being influencedby eddying or counter currents in the pipes. Thereby I am enabled toelimiate or avoid local excessive temperatures, such as would beuncomfortable to the patient. Moreover,by reason of the delivery of thedry air and the vapor into the cabinet and its thorough admixture beforeit rises into contact with the body of the patient, I am enabled tosecure a uniform mixture of the air and vapor, so as to apply as strongor as mild a treatment of the vapor tothe patient as desired while, atthe same time, I am enabled to regulate the temperature of the resultantmixture without varying the proportions as to vapor and dry air. f

The location vof the perforations of the pipes on the lower sidesthereof contributes to a more efficient mixing ofthe heated air andvapor, inasmuch as the air and vapor rise-0n both sides of the pipesfrom their points of discharge through the perforations` so that therising streams of air and vapor cross each other in larger areas ofcontact than ifA the air and Vapor escaped wholly through perforationsat the tops of the pipes.

Preferably the dry air pipe is placed between. the members of the vaporpipe. A practical advantage of this arrangement is that it is usuallydesirable to shut oil' the dry air before the vapor is shut olii. andtlu` arrangement of the vapor pipe adjacent to the sides of the cabinet,especially when provided with bottom perforations, allords superiordistribution of the vapor to the body of the patient.

It is preferable to arrange the outlet terminal of one pipe adjacent tothe inlet of the other pipe. In this way, the hottest air is broughtinto contact with the coolest vapor and vice versa, thus contributing tothe maintenance of an approximately uniform'temperature throughout thecabinet.

In practice. it is preferable to arrange the perforations in the pipes1S, 19 olf the center lines of the pipes, with the perforations ofadjoining limbs of different pipes located on the sides of the pipesadjacent to each other, as indicated in dotted lines in Fig. 3 and infull lines in Fig. This relative arrangement of the perforations directsthe vapor and dry air which issues from the adjoining limbs of the pipestoward each other so as to thereby assist in the proper admixturethereof.

I claim as my invention l. A therapeutic cabinet comprising an elongatedinclosure, a foraminated support stretched across the same,non-communicating heated medium and vapor pipes arranged side by sidewithin the inclosure beneath said support and extending from end to endthereof and perforated throughout their lengths at their lower sides ina inanner to interiningle the material escaping from the pipes in aplane below the pipes. said pipes extending through one wall of theinclosure, with separate means exterior to said wall to supply heatedmedium and heated vapor to the respective pipes, and the pipes beingarranged to provide free and unhampered passageways for the materialtherethrough whereby the heated medium and vapor are distributeduniformly to the inclosure throughout the length of the inclosure andintermixes and rises upwardly through the foraminated support, andseparate exhausts for said pipes extending outside the casing.

2. A therapeutic cabinet comprising an elongated inclosure, aforaminated support suspended thereacross, a U-shaped heated medium pipewithin the inclosure below said support with its induction end extendingthrough one wall of the inclosure, means to supply a heated medium tosaid pipe, a separate U-shaped vapor pipe within the inclosure with itslimbs lying between the limbs of the heated medium pipe and the sidewalls of the inclosure, and with its induction end extending through thewall of the inclosure, and means to supply a heated vapor to theinduction end of the vapor pipe, said pipes being perforated throughouttheir lengths in a manner to inter-mingle the heated media dischargedtherefrom in a plane below the pipes whereby the mixed heated medium andvapor rise upwardly through the foraniinated support.

3. A therapeutic cabinet comprising an elongated inclosure, aforaminated support suspended thereacross, a U-shaped heated medium pipewithin the inclosure below the said support with its induction endextending through one wall of the inclosure and with the eduction endextending outside the inclosure, means to supply a heated medium to saidpipe, a U-shaped vapor pipe within the inclosure with its limbs lyingbetween the limbs of the heated medium pipe and the side walls of theinclosure, and with its induction and eduction ends extending to theexterior of the inclosure, means to supply a heated vapor to theinduction end of the said vapor pipe, said pipes being perforatedthroughout their lengths, whereby the heated medium and Vapor escapingtherefrom intermingle within the inclosure and rise upwardly through theforaininated support, the induction end of the said heated medium pipebeing located closely adjacent to the eduction end of the vapor pipe,and Vice Versa.

4. A therapeutic cabinet comprising an elongated inclosure, an elongatedsupport therein for the patient, non-communicating pipes within theinclosure below the said support and arranged side by side throughoutthe length of the inclosure and provided with separate outlets andseparate means to supply material to the induction ends of the saidpipes, said pipes being provided within the inclosure with escapeopenings to direct the different material downwardly and toward eachother whereby the materials are intimately interiningled before theyrise to said support.
